Pennsylvania State Police have closed a homicide case that puzzled investigators for more than 40 years.

According to the release, Nestor Quintanal has been accused of taking the life of Edwin Rodriguez.

Mercer County District Attorney Peter Acker recently reviewed the case and said homicide charges would have been filed against Nestor Quintanal if he was alive today.

Quintanal passed away in Florida in 2002 at the age of 71.

The investigation into Rodriguez's death began on November 6, 1980 when a burning body was found near Interstate 80 in Wolf Creek Township.

At the time, the autopsy determined that the victim was a white male between 16 and 19.

Rodriguez, a Chicago native, was not identified until 2019 after advanced testing and screening were done to get a DNA profile from the victim in 2007.

The DNA profile was sent to Parabon NanoLabs for DNA Phenotype testing and a genetic genealogy screening, which led to a cousin of the victim and then to Rodriguez's identification.

Further investigation found that Quintanal was a family friend and that he and Rodriguez left Chicago for Florida in the fall of 1980.

After the two left Chicago, family never heard from Rodriguez again.

His remains have since been returned to his family.
